A Modern Day Renaissance of a Truly British Brand. Halcyon Days was founded in 1950 as an emporium of antique gifts in London. Today the company has evolved into a strong lifestyle brand as they continue to create their signature enamel pieces. Halcyon Days is one of only fourteen companies to hold all three Royal Warrants. This important relationship sets the high standard of UK craftsmanship and design, which they are dedicated to maintaining.
